layouts per action

[dc]

hi all -

Merb has a layout method for setting html layout to use -per
controller- but is there a recommended way to get per-action layouts
(or remove layout) ?

with Rails:
layout 'blah', :except =>[:a1, a2]

I guess:

def action
render :layout => 'blah'


works but its a bit of a pain to spec the layout in each action.

tx,

/dc

before :pick_layout

protected

def pick_layout
pick = ...
self.class.layout(pick)
end

Actually, unless it's changed recently, you should be able to simply
do this:

layout :determine_layout

protected

def determine_layout
'foo'
end


However, I don't know if / how you can find out which action is being
processed right now, so you can use this to determine which layout to
render.

sources say you still can do that :)

action_name should tell you which action is being processed.

thanks for the tips everyone.
FWIW we ended up adding this:


module Merb::RenderMixin
include Merb::ControllerExceptions

def layout(layout, options)
self._default_render_options ||= {}
if options[:only]
only = (options[:only].is_a?(Symbol) ? [options[:only]] :
options[:only])
self._default_render_options.update(:layout => ((layout &&
only.include?(action_name.to_sym)) ? layout : false))
elsif options[:exclude]
exclude = (options[:exclude].is_a?(Symbol) ?
[options[:exclude]] : options[:exclude])
self._default_render_options.update(:layout => ((layout && !
exclude.include?(action_name.to_sym)) ? layout : false))
else
self._default_render_options.update(:layout => (layout ?
layout : false))
end
end
end


# so now we can do:

class Profiles < Application

before lambda{|c| c.layout choose_layout, :exclude => :play}



its a bit more long-winded than i would like...
